The IMT-2020 summit in Beijing is held in Beijing with the "5G Commercial Win-Win Future", IMT-2020 (5G) Promotion Group Leader Wang Zhiqin announced the latest test progress of 5G terminal chips, Huawei Haisi's Baron 5000 chip can support NSA / Two modes of SA have completed all network tests from indoors to outside.
Huawei Haisi's Baron 5000 chip looks from two tests for SA and NSA, and Heith has completed all content; Qualcomm Participation is mainly X50 chip, the design of NSA, and completed comprehensive testing; The chip content is the SA and NSA, which is currently completed in all indoor tests, and outdoor performance tests are also progressing in progress; the test of violet exhibition is starting.
It is reported that Huawei Haisi's Balong5000 chip looks from two tests of SA and NSA from the design, and Haisi has completed all the content. Qualcomm participates in the test of the X50 chip, the design of NSA, has also completed comprehensive testing. The chip content of the Unicard is SA and NSA, which is currently completed in all indoor tests, and outdoor performance tests are also in progress. The test of the violet exhibition is starting. Like Haisi completed a more manufacturer's test, Qualcomm mainly NSA's function, and the test work in indoor and outdoor manufacturers is also overwritten, especially with Samsung. Work in Lianfa and Violet Exhibition, and the cooperation of some manufacturers is more prominent.
From the test content, one is a test work of the peak throughput of the indoor terminal, so from the entire test result, after a period of debugging, the terminal chip can generally reach the transmission performance of more than 80% of the theoretical peak value, so At 3.5 g, whether NSA or SA, the downlink peak rate is basically 1.3 to 1.5 Gbps. 2.6GHz Downstream in two modes is around 1.5 to 1.8 Gbps. The downlink peak of NSA and SA is basically quite.
Upstream transmission performance, in 3.5G frequency band, upstream peak test in NSA mode is 170Mbps, sag, will have an increase in 270Mbps. At 2.6 g of the same result, NSA is 130Mbps, and SA can be raised to 160 Mbps or more. So we believe that in SA mode, upstream can achieve a duplex, and there is still a significant increase in terms of speed.
Interoperability testing also uses mobile phones to perform actual peak rates in actual external fields, from the entire performance conditions, and indoor results are also a good verification. Downstream can reach a gigabit download rate, and the upstream is basically in 100 megabytes. So this picture on the left is downward, and the right is up. Under the conditions of NSA, the downstream is 1.0 to 1.4Gbps, and SA is basically in this value, and the upstream is different, and the upstream NSA is 100 to 170 Mbps, and SA can reach 240 to 280Mbps.
Interoperability test has a business long-term maintenance test. The entire business is continuously operated in a long time, so from the performance of the current test, the tests of each chip can basically reach the 360 to 760 Mbps average throughput, which is also a perceived perception of the future. The handover success rate is also better, reaching 100%.
In addition, everyone is focused on 3.5G, so we started to promote the entire industry in 2.6GHz this year and last year, it also clarified its frame structure. So the whole half a year, it also promotes a better effect with the operator. At present, 5 companies have a relatively complete 2.6G test in terms of functional, radio frequency and external performance, and the entire performance level has reached and 3.5 G-band comparable industrial maturity.
